Print ArticleWith digital flatbed printers making more inroads into the banner and graphics industries, the need for effective substrate holddown remains high. Be they digital, screen, or other, experienced printers all recognize the advantages of a vacuum holddown table, especially when it comes to accurate registration. One company that specializes in the production of precision vacuum holddown tables for any flatbed application is Graphic Parts International Inc. (GPI), a Chicago based manufacturer and global supplier of OEM vacuum holddown tables.
To achieve the perfectly flat surface required for high-quality printing, GPI vacuum tables are manufactured using a proprietary Stay-Flat process. Built around an all-aluminum honeycomb core for maximum airflow and covered with the thickest top and bottom plates for extra strength, the non-oxidizing, anodized aluminum tabletop resists warping and is extremely durable. For tougher applications GPI offers a stainless-steel surface, as well as Formica and phenolic tabletops for material sensitive and non-conductive applications. If you want to restore the performance of your existing vacuum table without the expense of purchasing a new one, GPI also offers resurfacing services to provide like new finish and flatness to your tabletop. Oversized substrates are no problem for GPI either, who produces the world's largest vacuum table at 10 by 25 feet with a 250 sqft surface of highly controlled holddown.
The maintenance-free vacuum motors that drive the system feature a multi-stage centrifugal design to quickly and quietly provide the proper amount of holddown. In addition to reducing noise, these brushless motors never need lubrication and improve workplace safety because they emit no sparks. Available in a range of configurations to suit various application requirements, each vacuum table is custom built to specification at the company's main production facility and world headquarters in Chicago, IL.
